Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Before the vehicle, the power-off method and device for the vehicle provided by the present disclosure and the vehicle are introduced, an application scenario related to various embodiments of the present disclosure is first described. The application scenario includes a vehicle provided with a BCM (Body Control Module, chinese) and various sensors for collecting status information. The vehicle can be an automobile, and the automobile is not limited to a traditional automobile, a pure electric automobile or a hybrid automobile, and can be suitable for other types of motor vehicles. Wherein the sensor for collecting the state information may include: a vehicle speed sensor, a gear sensor, a pressure sensor on a seat, and the like.
FIG. 1 is a flow chart illustrating a method of powering down a vehicle, as shown in FIG. 1, according to an exemplary embodiment, the method comprising the steps of:
step 101, obtaining the state information of a vehicle, wherein the state information comprises: a vehicle speed and a state of a target cover, the target cover comprising: a hood of a vehicle, and/or a fuel tank cap.
And 102, when the vehicle speed is zero and the target cover is opened, controlling the vehicle to be powered off.
For example, vehicles often encounter situations that require refueling or maintenance during use. In the process of the refueling state and the maintenance state, the vehicle needs to be powered back in advance to ensure the safety of the vehicle and a driver. Firstly, a vehicle speed sensor arranged on a vehicle can acquire the current vehicle speed, the vehicle speed sensor can send the vehicle speed to a BCM of the vehicle, and further, the BCM can detect whether the state of a target cover is opened or closed (namely, the state of a switch corresponding to a switch on the target cover). The target cap may include, among other things, a hood of the vehicle, and/or a fuel tank cap. To refuel the scene, BCM can detect the state of fuel tank cap, and to the maintenance scene, BCM can detect the state of bonnet.
When the BCM detects that the current vehicle speed is zero and the target cover is opened, the current refueling state or the maintenance state of the vehicle is determined, and the vehicle can be controlled to be powered off so as to ensure the use safety of the vehicle.
In summary, the present disclosure first obtains the status information of the vehicle, where the status information includes the vehicle speed and the status of the target cap, and the target cap may include a hood of the vehicle and/or a fuel tank cap, and when the vehicle speed is zero and the status of the target cap is open, the vehicle is controlled to power off. Can need not driver manually operation when the vehicle is in refuel or the maintenance scene, control vehicle moves back the electricity, has improved the degree of safety and the convenient degree that the vehicle used.
Further, the controlling of the vehicle power-off in step 102 may be: controlling a high voltage module of a vehicle to de-energize, wherein the high voltage module is a module that is powered through a high voltage loop, and may include, for example: the Power battery, the driving motor and the Power Distribution Unit (abbreviated as PDU) of the vehicle may further include: DC/DC, OBC (English: On BoardHarge, Chinese: vehicle charger), and the like.
Fig. 2 is a flowchart illustrating another power-off method for a vehicle according to an exemplary embodiment, where the target cover is a hood of the vehicle, and the status information may further include: and (4) gear state. Step 102 may be implemented by:
and step 1021, when the vehicle speed is zero, the gear state is the parking gear, and the hood state is open, acquiring the user state, wherein the user state is the in-vehicle state or the out-vehicle state.
The user status in step 1021 may be determined by the seat status on the vehicle, for example, the seat status of the vehicle may be obtained first. And when the seat state is unmanned, determining that the user state is the vehicle-outside state. And when the seat state is a person, determining that the user state is an in-vehicle state. Furthermore, images in the vehicle can be acquired in real time through an image acquisition device arranged on the vehicle, and whether a person exists in the vehicle is judged through an image recognition algorithm, so that the state of the user is determined.
And step 1022, controlling the vehicle to power off when the user state is the vehicle external state.
And step 1023, when the user state is the in-vehicle state, sending out prompt information, controlling the vehicle to power off, wherein the prompt information is used for prompting whether the vehicle is in a maintenance state.
For example, a gear sensor may be further provided on the vehicle to acquire a current gear state, and likewise, the gear sensor may transmit the gear state to the BCM. For a scenario where the vehicle is in a service state, then the target cover is the hood of the vehicle. When the vehicle is out of order and needs to be repaired, the driver usually takes the vehicle to check the engine condition of the vehicle, so that the user state, i.e., whether the driver leaves the vehicle, can be further judged to determine whether to control the vehicle to power off. For example, on the premise that the vehicle speed is zero, the shift state is a parking range (i.e., a P range), and the state of the hood is open, the user state may be further obtained, where the user state includes an in-vehicle state and an out-vehicle state, and corresponds to the driver being in the vehicle and the driver being out of the vehicle, respectively. And when the user state is determined to be the vehicle-outside state, directly controlling the vehicle to power off. When the user state is determined to be the in-vehicle state, prompt information can be sent out firstly to prompt the user whether the current vehicle is in a maintenance state, and meanwhile, if the vehicle is still powered on when the engine cover is in an open state, potential safety hazards exist, so that in order to guarantee the safety of the user, the vehicle is controlled to be powered off while the prompt information is sent out. The prompt information can be displayed in the form of characters or images through a central control display screen of the vehicle, and can also be played in the form of voice through a loudspeaker of the vehicle.
The seat state of the vehicle may be determined as an in-vehicle state or an out-vehicle state by determining whether the seat state is a person or an unmanned state based on a pressure sensor provided in the seat, for example. For example: and comparing the current pressure value acquired by the pressure sensor with a preset pressure threshold, determining that the seat state is manned when the current pressure value is greater than the pressure threshold, and determining that the seat state is unmanned when the current pressure value is less than or equal to the pressure threshold. And under the condition that the seat state is determined to be unmanned (namely the user state is the vehicle-outside state), the vehicle is controlled to be powered off.
The seat state may be a state of the main driver seat or a state of all seats in the vehicle. For example, if the seat status is the status of the primary driver seat, then step 1022 may simply determine whether the primary driver seat is occupied, i.e., control the vehicle to power down when the driver is away from the vehicle, and if the seat status includes the status of all seats in the vehicle, then step 1022 may determine that the driver and all passengers in the vehicle are away from the vehicle and control the vehicle to power down again.
Further, step 1023 can also be implemented by:
1) and when the user state is the in-vehicle state, sending out prompt information.
2) And receiving a confirmation instruction, wherein the confirmation instruction is used for confirming that the vehicle is in a maintenance state.
3) After receiving the confirmation instruction, the state of the hood is acquired.
4) And when the state of the engine cover is open, controlling the vehicle to be powered off.
For example, when a vehicle is out of order and needs to be repaired, the driver may not get off the vehicle, but check the engine condition by other people, for example, the driver is required to cooperate with stepping on the brake and the clutch to check the failure. Therefore, when the seat state is a person, that is, the driver does not leave the vehicle, a prompt message may be issued to prompt the driver whether the vehicle is in a maintenance state. The driver can send a confirmation instruction according to the prompt message to confirm that the vehicle is in the maintenance state currently. The confirmation instruction may be issued by a button provided on a vehicle console or a steering wheel, a command operation on a center control display screen, or a voice command, for example. After receiving the confirmation instruction, the state of the engine hood can be acquired after waiting for a preset time (for example, the preset time can be 3s), and when the engine hood is determined to be still opened, the vehicle is controlled to be powered off.
Further, under the condition that the vehicle is in the maintenance state, if the user state is the in-vehicle state, that is, the driver or the passenger does not leave the vehicle yet, another prompt message may be sent to prompt the driver to leave the vehicle. After another type of prompt message is sent, the seat state can be collected according to a preset interval until the seat state becomes unmanned. At this time, the preset time period (for example, the preset time period may be 3s) may be waited again, the state of the hood may be acquired again, and the vehicle may be controlled to power off under the condition that it is determined that the hood remains open.
In summary, the present disclosure first obtains the status information of the vehicle, where the status information includes the vehicle speed and the status of the target cap, and the target cap may include a hood of the vehicle and/or a fuel tank cap, and when the vehicle speed is zero and the status of the target cap is open, the vehicle is controlled to power off. Can need not driver manually operation when the vehicle is in refuel or the maintenance scene, control vehicle moves back the electricity, has improved the degree of safety and the convenient degree that the vehicle used.
